IPC: B01D45/18
Filed: 1985-03-05
Abstract: A plant for removing asbestos debris from an air stream which is drawn from a working area includes a collection and discharge hopper 8, comprising upper and lower parts 20 and 21 which are separable for individual transport on skip-loading vehicles. The hopper 8 comprises two identical hopper portions 25, each of which is arranged to be emptied via a chute 30, with which there is associated a fluid-tight cone valve 28 at the bottom of the respective hopper portion 25, and a membrane slide valve 31, disposed in the chute 30. By sequential operation of the valves 28 and 30, each hopper portion 25 may be emptied of debris, whilst the plant continues to function continuously. The debris passes from the chute 30 into a bag 33. Hopper 8 is arranged upstream of a second hopper (9), similarly provided with discharge valves 28, 30 and enclosing a bank of filter bags. Valves 28 are opened and closed by pneumatic bellows and vibrated to induce the flow of debris. <IMAGE>

Patent GB-2167857-A (GB)
Title: Ultrasonic gas flow metering apparatus
Inventor: REDDING ROBERT JAMES
IPC: G01H11/08
Filed: 1985-11-22
Abstract: Gas flow metering apparatus for use, for example, as a domestic gasmeter comprises two ultrasonic transducers (1, 2) spaced apart along a pipe (3) through which the gas flows. A frequency-modulated ultrasonic beam is fed through the gas flow from one transducer to the other, the direction of the beam being continually reversed by a switch unit (6) which connects one transducer to a frequency modulator (8) and the other to a demodulator (9) and repetitively reverses the connections. A phase comparator (10) compares the phase of the received modulation with the phase of the transmitted modulation and feeds a control voltage to a voltage- controlled oscillator (11) to cause the oscillator to adjust the modulation frequency so that a constant phase relationship is maintained. The difference between the control voltage values for each two successive beam direction changes gives a measure of the speed of gas flow. The voltage difference is integrated (13), and each time the integrated voltage reaches a predetermined level a pulse is fed to a store (15). Each pulse indicates the passage of a predetermined quantity of gas. <IMAGE>

Abstract: A modular sun tan system comprises a supporting structure e.g. a stand (10) which may be adjustable for height and which supports a canopy (15) on which a number of UVA modules (16) are mounted. Each UVA module (16) can be secured independently to the canopy (15) and is arranged to operate independently of the other UVA modules, having independent control means. In the example illustrated, the control means (35) include a ballast choke and capacitor for starting and maintaining the operation of the UVA lamp (29) which is a UVA emitting tube having a pair of lamp holders (30), the assembly being housed within a housing of extruded aluminium or plastics (23). Since each UVA module operates independently of the others, the number of modules (16) used in the canopy (15) can be varied according to the speed of tanning required or to cost or other criteria. <IMAGE>

Title: Control circuit for a bicycle lighting system
Inventor: VIDAL MIGUEL
IPC: B62J6/00
Filed: 1986-11-21
Abstract: If a light switch 18 is closed and a generator 11 is producing a low output, leakage current flowing through a triac 22 to its gate 25 causes a capacitor 30 to be charged from a rechargeable battery 21 via diode 26,27,28 whereby a diode 24 becomes forward biased to apply to a junction 23 a potential such as to cause triac 22 to conduct so that the battery 21 energises lamp 19. As the generator output rises above a certain level, the potential at junctions 15,17,23 will be such as to render triac 22 nonconductive and a diode 16 conductive so that the generator 11 energises lamp 19 and recharger battery 21. Experimental tests with a conventional generator 11 established that triac 22 is turned off when the bicycle speed reaches about 8 miles per hour. <IMAGE>
